Answer Posted / ravi
For parallel operation of transformers as you know the
requirements, 1. magnitude of the voltage, 2. phase angle
difference between the i/p and o/p voltages, 3. equal
percentage impedance of the transformers.
I don't think that whatever you are asked configurations
same vector symbol will get. So we can't do paralleling.
if you get the same phase angle difference ypu can go ahead
with paralleling.
